IMPROVEMENT IN CAR-HEATERS.

Specification forming part of Letters Patent No. 190,002, dated April 24, 1877 application filed February 20,1877.

To all whom it may concern:

Be it known that I, LE ROY CAPBON, of Akron,-in the county of Summit and State of Ohio, have invented an Improvement in .Safety (Jar-Heaters for Railway Passenger-Oars, of which the following is a specification:

My invention has relation to that class of car-heaters which consist of a furnace situated beneath the floor of the car; and it has for its objects to avoid the necessity of frequent attention to the fires; to secure the greatest neat from the fuel consumed; and to avoid all danger of fire in the event of accident.

at the line .00 w.

H is an upright cast-iron cylinder, which forms the combustion-chamber, at the bottom of which is a grate, and from which, intermedially between the bottom and top, issues the smoke-flue E, passing thence up through and out at the top of the car.

Fuel is introduced into the cylinder H at the top, which is made converging, and is closed by the door D, which can be securely locked down, and the top whereof is flush with the floor of the car.

At the bottom-of this cylinder is a damper, R, regulated by the rod F, which enters the interior of the car, and by which the combus tion of fuel may be regulated.

By this arrangement the furnace may be easily charged before starting with sufficient fuel to run for several hours.

I I is the hot-air chamber surrounding the cylinder H, and into which air enters through suitable apertures at or near the bottom. G, Figs. 1 and 3, is a large register on top of the chamber 1, through which hot air can be admitted to the car, when desired.

Hot air is also conveyed from this chamber through the pipes J J, cross-pipes K K, el-

the water remains in said tanks below the pipes 0; but if the car is excessively inclined, the water rushes through. the said pipes into the combustion chamber, and extinguishes the fire.-

M Mare auxiliary water-tanks, connected with the tanks N N by pipes O 0. These tanks are provided with feeding-pipes P P, and overflow-pipes 1) 1), so they can be filled from the outside of the car.

The whole is incased in a suitable compartment under the car, and the entire covering B of the furnace and attachments is of iron, by which arrangement no inflammable substance is brought in contact with heated surfaces.

When in use, the tanks N N and M M are filled with water to the overflow-pipe. As long as the car maintains its proper position the water remains in these tanks; but when excessively inclined in any direction, the water is discharged from some of them directly upon the fire, and extinguishes it at once.

I am aware that furnaces under cars, the heat of which is distributed through registers, are not new; but such of itself is not my invention.

I claim as my invention- 1. The combination of the tanks M and N, the cylindrical fire-chamber H, and the inter-' vening .annular hot-air chamber I, having openings for the admission of air, suhstantially as and for the, purpose described.

2. The combination, with the cylindrical fire-chamber H, of the annular tanks N N, pipes O O, auxiliary tanks M, and pipes O O, substantially as and for the purpose described.
